Hazardous chemicals are substances that can hurt us, or the environment, if we are not careful. They can be liquids, gases, dusts, or fumes, and can be found in many places, like factories and laboratories. They can also be used in products you may have in your home, like paints and solvents. Even something as common as bleach! Hazardous chemicals can cause a lot of health problems, like skin irritation and even cancer, so it is important for us to take safety measures when we come in contact with them. It is important to read labels carefully, follow safety instructions, and make sure we use protective clothing and eyewear when dealing with hazardous chemicals.
